    Public Methods
     NameDescription
    Public MethoddeflateCompresses as much data as possible, and stops when the input buffer becomes empty or the output buffer becomes full.  
    Public MethoddeflateEndFrees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output.  
    Public MethoddeflateInitOverloaded. Initializes the internal stream state for compression.  
    Public MethoddeflateParamsDynamically updates the compression level and compression strategy.  
    Public MethoddeflateSetDictionaryInitializes the compression dictionary from the given byte sequence without producing any compressed output.  
    Public MethodinflateDecompresses as much data as possible until the input buffer is exhausted or the output buffer is full.  
    Public MethodinflateEndFrees all dynamically allocated data structures for this stream, discards any unprocessed input, and does not flush any pending output.  
    Public MethodinflateInitOverloaded. Initializes the internal stream state for decompression.  
    Public MethodinflateSetDictionaryInitializes the decompression dictionary from the given uncompressed byte sequence.  
    Public MethodinflateSyncSkips invalid compressed data until a full flush point is found, or until all available input is skipped. No output is provided.
